Following last volume's confirmation that Yuki Suetsugu's Manga Taisho Award winning Chihayafuru manga would be getting a second season of anime, the newly released 18th volume of the acclaimed karuta drama included the notice that the anime will be returning in January 2013.
The Madhouse produced first series ran October, 2011 to March, 2012.
From Crunchyroll's description of the series:
Ayase Chihaya is a sixth grader whose dream is for her older sister to become the top model in Japan.
But one day, a transfer student, Wataya Arata, tells her that her dream should be about herself. Arata's dream is to become a famous competitive Karuta player. Chihaya is somewhat shocked when she sees how intense the normally reserved Arata gets about the card game. Eventually, she and her childhood friend Mashima Taichi find themselves being captivated by Karuta. Arata is thrilled by Chihaya's talent and extraordinary hearing, as well as the fact that he has friends to play Karuta with now, but they are forced to go their separate ways after graduating from grade school.
Four years later, Chihaya enters high school and discovers that Arata, who returned to Fukui, no longer plays Karuta. However, she believes that if she continues to play, they will one day be reunited. And so, she and Taichi start a Karuta club at Mizusawa High School.
The volume's release also featured a t-shirt lottery give-away
A prose short story concerning the character's middle school years was also released on the 13th.
